  • The Armpit Challenge

    Mentioned a few weeks ago - I thought I'd post this now for people to get prepped for the challenge.

    Aim:
    To get as many productive tomato plants as possible from one seed. Productive, means you harvest at least 10 ripe tomatoes from it. [My line in the sand, but we rely on your honesty].

    Hypotheses:
    As indeterminate tomato plants grow, it is common to remove the 'armpits' to keep production to the main stem. However, these armpits are in fact, potential new plants and can be treated as cuttings and be grown on.

    Equipment:
    One tomato plant [indeterminate]
    Pots
    Compost
    Labels
    Camera
    Notebook
    Pencil or keyboard
    The Vine

    Method:
    Grow a tomato plant from seed
    As the plant grows, remove each 'armpit' and place in water or compost for a week, until the plant stops drooping and recovers
    Pot on and treat as per any tomato plant
    Number each seedling that recovers, with the original plant numbered as '1'.
    As each plant produces a crop - take the tomatoes and record how many each plant has produced
    Record your figures and post on here your results.
    If you are feeling exceptionally scientific, you could weigh each crop, and also count the days from sowing to first and last cropping, and the time taken from nipping your armpits out to recovery and potting on, and first and last cropping.
    Record the dates that each plant comes to the end of it's cropping life

    Results - see below

    Compare and contrast:
    Did anything affect your armpits? What did you feed your plants? Did you use different feeds and compare the results?

    The person who crops from the most plants and produces a good account of the experience, with photos to support their experience, wins a bag of heritage seeds that include beans, peas, tomatoes and peppers/chilis.

    Even if you don't want to win, it would be interesting to hear each person's experience and accounts.

    Further research:
    Some plants and seeds are very very expensive - such as F1 Sungold. How much can you get each plant down to [price wise] by taking armpit cuttings? Can you take armpits from armpits and make your money go even further?
    How did blight affect your tomatoes, if indeed it did? Did the original plant get it first, or last?

    Sign up below to take part, or even if you are just interested in taking armpit cuttings and want to try a few.

    Note: as per usual, naysayers feel free to go start your own 'I'm not taking cuttings from armpits' thread.

    Do my 4 Robin F1 plants currently on my kitchen windowsill - descended from a single seed 3 years ago - count?

      This is sooooo Cool! I'm in! I really enjoyed the fact I got complete new plants in this way so will be interested to see how many plants I can get! And if my sideshoots provide sideshoots and they make more! Here we go!

        I'm not bothered about competing but am willing to give it a go just to see .....How big do side shoots have to be before you can use them ?

          I nipped mine at a few inches lasst year (3-4 maybe) and put them straight into a new pot. The flop a bit first but soon perk up! not sure I'll actually be competing as such but will be taking part of the speriment!

            Ooohhh, I want to join in! I love competitions!

            But I have a question...can we only do one plant? I was planning on "armpitting" a lot of mine just to save some valuable windowsill space.

                I did the same, as soon as I could comfortably grab them I pulled them off and to be honest, just banged them in the ground for an experiment - despite reading about putting them in water first..

                most of them grew, one was huge in the end. Left it a bit late in doing it, so no toms were ripe but them all went in the green tom chutney!

                  As long as you just choose one - but it would be good to sow one this year just for the trial...

                    You can do as many as you want - but you might get a little overwhelmed with all the numbering and recording...

                      Like Shirl - it would be best with one sown this year but if you want to choose one from last year's - I'm not gonna come round and check!

                        This sounds really interesting, I've always composted the armpits, even though I've read on here before about potting them up. I know I can't stick to recording the details, but I'll have a go at propagating some and will be interested in the results of those who keep proper records!

                          Umm, I can't get the seeds any more - hence keeping them going from one year to the next

                          I will join in with a more standard tomato plant

                              Would love to loin in but don't have the space as I can see this as being a large experiment. I don't usually bother with armpits as I usually have more than enough seed to grow all the plants I need from seed. Only a guess but I can envisage in excess of 30 plants in a season, don't know how many would get to producing 10 tomatoes. All very thought provoking.
